Randperm Function - Random Permutations

How can I use randperm for a nx2 matrix?

"randperm" only takes 1 scalar input argument. Can you give a sample of an input nx2 matrix AND what you would expect the output to be?

If you want to randomly permute the rows, do something like the following.

n = 5;

A = reshape(1:2*n, n, 2)

B = A(randperm(n), :)

if you want to randomly permute all elements, do something like this instead.

C = reshape(A(randperm(2*n)), n, 2)
